Description

터널형성용 터널구조물 시공방법 및 터널구조물 구조{Tunnel formation tunnel structure form of construction work and tunnel structure}Tunnel formation tunnel structure form of construction work and tunnel structure}

본 발명은 터널형성용 터널구조물 시공방법 및 터널구조물 구조에 관한 것으로, 더욱 상세하게는 본격적인 터널굴착을 하기 전에 터널을 시공하고자 하는 산악지역이나 지하철설치 지역 등의 지반에 알맞은 특수한 방법으로 원형형태의 견고한 터널구조물을 설치하여 터널구조물이 외부응력을 충분히 견디도록 함으로써 터널굴착이 안전하면서도 손쉽고 빠르게 이루어지도록 하여 공사기간을 단축하도록 함은 물론, 인력과 장비 그리고 자재 등의 소요를 현저하게 감소시켜 경제적으로도 도움을 주도록 하여 무엇보다 터널공사중이거나 터널완공 후 안전한 터널을 오래도록 지탱할 수 있게 하는 터널형성용 구조물을 형성하기 위한 것이다.The present invention relates to a tunnel structure construction method and a tunnel structure construction, and more particularly in a circular form in a special way suitable for the ground, such as mountain area or subway installation area to construct the tunnel before full-scale tunnel excavation By installing a solid tunnel structure, the tunnel structure can withstand the external stress sufficiently, making tunnel excavation safe, easy and fast, and shortening the construction period, and significantly reducing the labor, equipment, and material requirements. It is also intended to form a tunnel-forming structure that can support the tunnel for a long time during the tunnel construction or after the completion of the tunnel.

일반적으로 터널을 형성하기 위해서는 반드시 터널외부로부터 발생하는 응력에 견딜 수 있도록 터널구조물이 설치되는바, 이와 같은 터널구조물을 설치하기 위한 종래의 터널구조물 설치방법의 일 실시예를 설명하면 다음과 같다.In general, in order to form a tunnel, a tunnel structure is installed to withstand the stress generated from the outside of the tunnel, and thus, an embodiment of a conventional tunnel structure installation method for installing such a tunnel structure will be described below.

종래에는 터널굴착을 위해 굴착될 터널의 윤곽을 따라 원형형태로 드릴링 작업을 통해 다수의 구멍을 천공하여, 그 후에 보강 재로서 작용하는 일 방향 밸브가 구성되어 있는 튜브를 삽입하고, 상기 튜브 내로 패커(packer)가 선단에 구비된 경화재주입로드를 삽입하여 패커가 강관 끝단에 오도록 한 다음, 상기 패커를 서서히 후퇴시키면서 튜브 내로 그라우트경화재를 주입하여 튜브에 형성된 일 방향밸브를 통해 그라우트경화재가 외부로 흘러나가 지중내로 분사되도록 하여서, 분사된 그라우트재가 드릴링 작업에 의해 천공된 구멍에서 가장 멀리 떨어진 곳으로부터 가장 가까운 쪽으로 이동함으로써 토질을 석화시키는 작업을 수회 반복하여서 얻어진다.Conventionally, a plurality of holes are drilled in a circular shape along a contour of a tunnel to be excavated for tunnel drilling, and then a tube is formed, in which a one-way valve acts as a reinforcement, and a packer is inserted into the tube. (Packer) insert the hardener injection rod provided at the tip so that the packer comes to the end of the steel pipe, and then the grout hardener flows through the one-way valve formed in the tube by injecting grout hardener into the tube while slowly retreating the packer It is obtained by repeating several times the calcification of the soil by causing the injected grout material to move toward the nearest from the furthest from the hole drilled by the drilling operation.

이때 주입된 그라우트재와 절삭토가 서로 희석되어 배출되므로 토양 오염을 시키는 심각한 문제가 유발되었다.At this time, since the injected grout and the cutting soil are diluted with each other and discharged, serious problems causing soil contamination have been caused.

또한 종래의 터널구조물 구조를 볼 것 같으면 모두 석화기둥이 각각 소정의 간격을 두고 띄엄띄엄 형성되어 있음은 물론 삽입된 파이프 속에서 밸브 작동이 원활하지 못하여 상층의 개량효과가 기대에 못 미쳤고 틈새 폭이 크고 넓기 때문에 보다 안정된 지반을 얻기가 어려우며, 상기 틈새로 지하수가 유출되어 차수 역할을 전혀 할 수 없는 관계로 터널굴착작업을 시행할 시 굴착도중에는 물론이고 굴착 후 가시설공사시에 지반 또는 암반 등이 붕괴하거나 낙반될 염려가 매우 높아서 항상 안전사고의 발생위험이 있었다.In addition, if you look at the structure of the conventional tunnel structure, the petrification columns are all spaced apart at predetermined intervals, and the valve operation is not smooth in the inserted pipe. Because it is large and wide, it is difficult to obtain more stable ground, and groundwater is leaked into the gap, so the ground or rock can collapse during the construction work as well as during the excavation when performing tunnel excavation work. There was always a high risk of falling, or there was always a risk of a safety accident.

이에 틈새를 없애기 위해서는 더욱 많은 수의 석화기둥을 형성하는 작업을 하여야 하거나, 또는 터널내부시설을 더욱 견고하게 하여야 하므로 많은 인력과 장비 및 자재가 소요되어 작업이 비능률적이고 비경제적이었으며, 터널구조물의 지구력의 취약점 때문에 항상 터널붕괴 및 안전사고의 발생위험으로부터 벗어날 수 가 없는 등의 여러 가지 문제점을 안고 있었다.In order to eliminate the gap, the work to form a larger number of petrification columns or to strengthen the tunnel internal facilities required a lot of manpower, equipment, and materials, resulting in inefficient and inefficient economic endurance. Due to the weakness of the company, there were always various problems such as being unable to escape the risk of tunnel collapse and safety accidents.

본 발명은 상기와 같은 종래의 터널구조물 설치공법에서 발생하는 제반 문제점들을 해결하기 위해서 안출한 것으로,The present invention has been made to solve various problems arising in the conventional tunnel structure installation method as described above,

터널을 시공하고자 하는 산악지역이나 지하철시공지역 등의 지반조건을 고려하여 개량체를 형성하고자 하는 부위에 토층을 절삭하며 이때 절삭되어 외부로 배출되는 절삭토를 시멘트고화재와 배합하여 콘크리트경화재를 만들어서 절삭된 지중에 재충진하므로 개량체를 형성하도록 하는등 특수한 방법으로 터널 상층에 균등한 개량경 및 균질한 개량체를 조성하여 터널형상과 일치하도록 원형형상의 견고하고 튼튼한 터널구조물을 시공설치 할 수 있는 공법 및 이로부터 얻어지는 터널구조물구조를 제공하여서, 터널구조물이 외부응력을 충분히 견디도록 함은 물론, 배토된 절삭토를 다시 시멘트 고화재와 교반하고 재주입하여 환경오염을 방지 할 수 있도록 하고, 토사유출 및 차수 역활을 완벽하게 수행함으로써, 터널굴착이 안전하면서도 손쉽고 빠르게 이루어지도록 하여 공사기간을 단축하도록 함은 물론 인력과 장비 그리고 자재 등의 소요를 현저하게 감소시켜 경제적으로도 도움을 주도록 하였으며, 스라임을 재사용함으로 환경 친화적이고 무엇보다도 터널완공 후 안전한 터널을 오래도록 지탱할 수 있도록 함에 그 목적을 둔 것이다.In consideration of the ground conditions such as the mountain area or subway construction area where tunnels are to be constructed, the soil is cut at the part to be improved, and the cutting soil discharged to the outside is mixed with cement solids to make concrete hardeners. By refilling the ground, it is possible to construct a solid and sturdy tunnel structure in the shape of a circular shape to match the tunnel shape by creating a uniformly improved diameter and a homogeneous improvement body in the upper layer of the tunnel by special methods such as forming an improved body. By providing a construction method and a tunnel structure obtained therefrom, the tunnel structure can withstand the external stress sufficiently, and also to prevent the environmental pollution by agitating and re-injecting the excavated cutting soil with cement solidified material, The tunnel excavation is safe and easy In addition to shortening the construction period and reducing the manpower, equipment, and material requirements, it is also economically helpful. The purpose is to make it supportable.

상기와 같은 목적을 달성하기 위한 본 발명을 터널을 시공하고자 하는 산악지역이나 지하철시공지역 등의 지반조건에 따른 굴착방법 즉, 터널을 시공하고자 하는 산악지역이나 지하철공사지역의 지반이 토사로 이루어진 지형인 경우에 모든 자재 및 인원의 출입구가 되는 작업구(전진기지)를 마무리 한 상태에서,Excavation method according to the ground conditions of the mountain area or subway construction area, such as to construct the tunnel according to the present invention for achieving the above object, the terrain consisting of the soil of the mountain area or subway construction area to construct the tunnel In the case of finishing work tool (forward base) which becomes the entrance of all materials and personnel in case of,

터널을 뚫고자 하는 위치의 지중 내부에 터널형태를 이루도록 응력재파이프(50)를 일정한 간격으로 타입하여 지반을 개량강화한 다음, 그 상측의 지반을 절삭함과 동시에 콘크리트경화재(40a)를 충진하여 빈틈없이콘크리트경화체(40)를 형성하는 공법을 첨부도면에 의거 상세히 설명하면 다음과 같다.In order to form a tunnel inside the ground where the tunnel is to be drilled, the stress pipe 50 is formed at regular intervals to improve the ground, and then the ground on the upper side is cut and the concrete hardening material 40a is filled to fill the gap. Referring to the method of forming a concrete hardener 40 without reference to the accompanying drawings in detail as follows.

본 발명은 첨부도면 도1 내지 도2에 도시된 바와 같이 먼저 터널진행방향으로 상향 경사지게 터널과 같은 형태인 원형형태가 되도록 소정간격으로 소구경의 응력재파이프(50)를 압입 설치하여 지중의 토압에 의한 외부응력이 응력재파이프(50)에 고르게 전달되어 보강 작용함으로써 안정된 지반층을 형성하는 응력재파이프설치공정을 수행한다.In the present invention, as shown in the accompanying drawings, Figures 1 and 2, first, the pressure reinforcing pipe 50 having a small diameter is press-installed at predetermined intervals so as to be circularly shaped like a tunnel so as to be inclined upward in the tunnel progress direction. The external stress by the evenly transmitted to the stress material pipe 50 to perform a stress material pipe installation process to form a stable ground layer by reinforcing action.

이와 같이 하여 외부응력에 대응하여 안정된 지반층을 얻은 다음에는 상기 응력재파이프(50)상측에 빈틈없이 콘크리트경화체(40)(40')를 빈틈없이 조성하여야 하는데,In this way, after obtaining a stable ground layer corresponding to external stress, concrete hardeners 40 and 40 'must be formed on the stress material pipe 50 without any gaps.

이와 같이 하기 위해서는 콘크리트경화체(40)를 먼저 소정간격으로 순차적으로 형성하고, 그 다음에는 기 시공완료된 콘크리트경화체(40)사이에 또 다른 콘크리트경화체(40')를 맞물리도록 순차적으로 형성시켜야 한다.In order to do this, the concrete hardening body 40 must be sequentially formed at predetermined intervals first, and then, the concrete hardening body 40 'must be sequentially formed to engage another concrete hardened body 40' with the construction completion.

이와 같은 콘크리트경화체(40)(40')를 형성하는 콘크리트경화체조성공정을 더욱 상세히 설명하면 다음과 같다.The concrete hardening body forming process of forming such concrete hardeners 40 and 40 'is described in more detail as follows.

먼저 첨부도면 도3 내지 도4에 도시된 바와같이 콘크리트경화재(40a)와 절삭수(31)와 에어(32)를 동시에 주입할 수 있는 삼중관으로된 천공로드(30)를 이용하여 지중에 소정깊이로 작업공을 천공하는 천공공정을 수행하고,First, as shown in the accompanying drawings, FIGS. 3 and 4, the concrete hardening material 40a and the cutting water 31 and the air 32 are formed by using a triple pipe punching rod 30 capable of simultaneously injecting the soil into the ground. Perform the drilling process to drill the worker to the depth,

상기 천공공정에서 천공공정을 완료한 천공로드(30)를 서서히 인발하면서 고압의 에어(32)가 분사되어 이루는 에어통로 내부로 고압의 절삭수(31)를 분사함과동시에 고압의 에어(32)를 분사하여 에어커팅층(32a)을 형성하면서 절삭된 지중으로 콘크리트경화재(40a)를 강제 압입하여 충진함으로서, 상기 절삭수(31)에 의하여 절삭된 절삭토(61)는 외부로 배토되면서 지중에는 콘크리트경화체(40)(40')가 조성되도록 하면 된다.Injecting the high pressure cutting water 31 into the air passage formed by spraying the high pressure air 32 while gradually drawing the drilling rod 30 having completed the drilling process in the drilling process and at the same time the high pressure air 32 By spraying and filling the concrete hardening material 40a with the ground cut by forming the air cutting layer 32a, the cutting soil 61 cut by the cutting water 31 is discharged to the ground while What is necessary is just to make concrete hardening body 40 (40 ').

이때, 상기 콘크리트경화체(40)(40')가 전방으로 상향경사지게 형성되므로 콘크리트경화재(40a)가 높이가 낮은 후방으로 흘러나올 염려가 있으나, 본 발명에서는 콘크리트경화재(40a)가 지중으로부터 배토되는 절삭토(61)를 이수분리하여 시멘트고화재와 단단하게 반죽하여 주입하므로 개량체에서 유출되는 일이 없다.At this time, since the concrete hardener 40, 40 'is formed to be inclined upwardly forward, there is a fear that the concrete hardener 40a flows out to the rear with a low height, but in the present invention, the concrete hardener 40a is cut from the ground. Soil (61) is separated by dilution and solidly kneaded with cement solidifying material so that it does not leak from the improved body.

그러는 한편, 마지막 마무리 단계에서는 일정거리(L) 만큼은 남겨둔 상태에서 절삭수(31) 공급을 중단하여 지반(60) 절삭을 중지한 상태에서 에어압을 서서히 감압하다가 중지시켜서 마지막까지 콘크리트경화재(40a)가 충진되도록 한다.On the other hand, in the final finishing step, the cutting water 31 is stopped while leaving a certain distance (L) and the air pressure is gradually reduced while stopping cutting of the ground (60). Allow to be filled.

상기한 공정을 수행시에는 에어커팅층형성용 에어(32)에 의해 에어커팅층(32a)이 형성되면서 상기 콘크리트경화재(40a)에 절삭토(61)가 침투하여 섞이는 것이 방지되며, 기 충진된 콘크리트경화재(40a)가 배토되는 것 또한 방지된다.When the above process is performed, the air cutting layer 32a is formed by the air cutting layer forming air 32, and the cutting soil 61 is prevented from penetrating into the concrete hardener 40a and mixed with the air cutting layer 32a. The discharge of concrete hardener 40a is also prevented.

상기와 같이 콘크리트경화재(40a)가 충진완료되면 첨부도면 도4에서와 같이 천공로드(30)를 빼내고 콘크리트경화재(40a)가 흘러나오지 못하도록 테이퍼진 목재마개(70)를 이용하여 막는작업을 수행하면 콘크리트경화재(40a)가 굳으면서 안정적인 콘크리트경화체(40)(40')를 얻을 수 있는 것이다.When the filling of the concrete hardener 40a is completed as described above, the drilling rod 30 is pulled out as shown in FIG. 4 and the blocking operation is performed by using the tapered wood stopper 70 to prevent the concrete hardener 40a from flowing out. As the concrete hardening material 40a hardens, it is possible to obtain stable concrete hardening bodies 40 and 40 '.

이와같은 본 발명의 일 실시예에 의해 완성된 터널구조물은 터널을 시공하고자 하는 산악지역이나 지하철시공지역 등의 지반조건이 즉, 지반이 주로 토사로 이루어진 지형인 경우 먼저 터널굴착 전에 소정간격으로 응력재파이프(50)를 삽입 설치하여 안정된 지반을 얻은 다음,Tunnel structure completed by an embodiment of the present invention as described above, if the ground conditions, such as mountain area or subway construction area to construct the tunnel, that is the terrain mainly composed of earth and sand stress first at a predetermined interval before tunnel excavation After inserting the re-pipe 50 to obtain stable ground,

그 상측에 일체화된 콘크리트경화체(40)(40')를 형성하되, 먼저 콘리트경화체(40)를 소정간격으로 띄엄띄엄 순차적으로 형성하고 그 다음에는 상기 띄엄띄엄 선 시공 완료된 콘크리트경화체(40)사이에 또 다른 콘크리트경화체(40')를 순차적으로 형성시켜서 이루어지는 터널형성용 터널구조물로써,The concrete hardening body 40 (40 ') is formed on the upper side, but the concrete hardening body 40 is formed at a predetermined interval in a stepwise order, and thereafter, the spaced between the completed concrete hardening body 40 As a tunnel structure tunnel structure formed by sequentially forming another concrete hardening body 40 ',

본 발명에 의하여 개량강화된 지중에 터널굴착작업을 시행하게 되면 터널의 내부 천정부분을 이루는 콘크리트경화체(40)(40')가 빈틈없이 형성되어 지반이 안정되게 개량된 터널구조물이 외부응력을 충분히 견디도록 선 시공되어 있으므로 토사유출 및 차수역활을 완벽하게 수행함으로써, 터널굴착이 안전하면서도 경제적이며 손쉽고 빠르게 이루어진다.When the tunnel excavation work is performed in the ground reinforced by the present invention, the concrete hardened body 40, 40 'forming the inner ceiling portion of the tunnel is formed tightly so that the ground structure is stable and the tunnel structure sufficiently improves the external stress. Since it is pre-constructed to endure, the excavation and drainage of the soil is performed perfectly, making tunnel excavation safe, economical, easy and quick.

상기와 같이 본 발명은 터널공사를 함에 있어서 미리 터널굴착을 시행하지 않고 터널을 시공하고자 하는 산악지역이나 지하철시공지역 등의 지반조건에 따라 가장 알맞은 특수한 방법 즉, 공사전이나 공사도중에도 토사층이나 연약층이 발견될 시 먼저 터널진행방향과 같은 방향으로 상향경사지게 다수의 응력재파이프를 강제 삽입하여 안정된 지반을 얻은 후,As described above, the present invention is the most suitable special method according to the ground conditions, such as mountain area or subway construction area to construct the tunnel without performing tunnel excavation in advance in the tunnel construction, that is, the soil layer or the soft layer during the construction or during the construction. When this is found, first, a number of stress reinforcing pipes are forced to be inclined upward in the same direction as the tunnel progress direction to obtain stable ground.

상기 응력재파이프 상측에 천공로드를 소정의 깊이까지 천공하여 고압수로 절삭하면서 콘크리트경화재를 강제 주입하고 응력재파이프와 일체가 되도록 양생하여서, 터널내부 천정부분을 이루는 콘크리트경화체가 빈틈없이 형성되도록 하는 터널구조물시공방법을 사용하여 터널구조물을 선 시공함으로써,The drill rod is drilled on the upper side of the stress material pipe to a predetermined depth to inject concrete hardening material while cutting with high pressure water and curing to be integrated with the stress material pipe, so that the concrete hardening body forming the ceiling part inside the tunnel is formed without gap. By constructing the tunnel structure using the tunnel structure construction method,

터널굴착시 터널의 내부 천정부분을 이루는 콘크리트경화체가 빈틈없이 형성되어 지반이 안정되게 개량된 터널구조물이 외부응력을 충분히 견디도록 선 시공되어 있으므로 토사유출 및 차수역활을 완벽하게 수행함으로써, 터널굴착이 안전하면서도 경제적이며 손쉽고 빠르게 이루어짐은 물론,When tunnel excavation, the concrete hardening body which forms the inner ceiling part of the tunnel is formed without gaps, and the tunnel structure with improved ground stability is pre-installed to withstand the external stress sufficiently so that the excavation of the tunnel is completed by performing the sediment drainage and the order role. It's safe, economical, easy and fast,

콘크리트경화체를 얻기위한 콘크리트경화재 충진작업중에 지중에서 배토된 절삭토와 시멘트고화제를 외부에서 사용목적에 부합 되도록 배합하여 단단하게 반죽된 상태의 충진재를 압력을 가하여 주입하므로 상향 경사지게 형성된 충진된 콘크리트경화재가 유출되는 것을 사전에 억제시킬 수 있므므로 이와같이 하여 조성된 콘크리트경화체가 균등한 개량경을 확보하고 균질한 개량체로 형성되며, 저 강도부터 고 강도까지 임의로 설정하여 시멘트고화제를 알맞게 사용함으로서 시멘트고화제의 수요량을 현저히 줄일 수 있어 경제적이며, 기 주입된 콘크리트경화재와 이녕화된 절삭토 사이에 에어노즐에서 분사된 에어가 에어커팅층을 형성하므로 콘크리트경화재가 배출되는 일이 없어 스라임이 발생되지 않으므로서 환경친화적이고 경제적임은 물론, 콘크리트경화재에 절삭토와 섞이는 일이 없어 지반 내에서 더욱 강건하게 경화되도록 하여 지반이 더욱 튼튼하게 개량 강화된다.During the filling process of concrete hardener to obtain concrete hardener, the cutting soil and cement hardener, which are disposed in the ground, are mixed to meet the purpose of use, and the filler is hardly kneaded. Can prevent the outflow of gas in advance, and thus the concrete hardened body formed in this way secures an even improved diameter and is formed into a homogeneous improved body.The cement hardener can be appropriately set by arbitrarily setting low strength to high strength. It is economical because it can significantly reduce the demand of the topic, and the air sprayed from the air nozzle forms an air-cutting layer between the pre-injected concrete hardener and the incinerated cutting soil, so no concrete hardeners are discharged and no slime is generated. Eco-friendly and economical Ron, no work on concrete settable material cutting and mixing soil to ensure more robust cured in the soil is improved to enhance the soil and more durable.

따라서, 본 발명은 지반침하 및 누수로 인해 각종 터널이나 구축물 등이 붕괴위험으로부터 벗어나므로 터널굴착이 안전하면서도 손쉽고 빠르게 이루어지도록 하여 공사기간이 크게 단축되는 것은 물론, 인력과 장비, 자재 등의 소요가 현저하게 감소되어 경제적으로도 도움이 되며, 무엇보다도 터널완공후 안전한 터널을 오래도록 지탱할 수 있도록 하여 수명이 장구하게 되는 등의 여러가지 효과가 있는 매우 획기적인 발명이다.Therefore, in the present invention, various tunnels and structures are released from the risk of collapse due to ground subsidence and leakage, so that tunnel excavation is made safe and easy and fast, and the construction period is greatly shortened. It is significantly reduced and economically beneficial, and above all, it is a very innovative invention with various effects such as long life can be supported by long-lasting a safe tunnel after completion of the tunnel.
